Application April 18, 1955, Serial No. 502,035

3 Claims. (Cl. 118-268) The present invention relates generally to applicators, and more particularly to a novel device for applying liquid cement in a predetermined pattern on the surface of a plastic article.

The increasing use of plastics as a base material for numerous articles of manufacture is, of course, due in large part to the facility with which plastic parts may be mass produced. In many instances, plastic parts are joined together in the construction of plastic articles, and the method of securement generally resorted to involves the application of liquid cement to at least one of the parts and then pressing the parts together. Not infrequently, it is desired to apply the liquid cement in narrow strips or in small spots, and there are many occasions when it is desired to apply the cement to as many as a dozen or more different spots on the same article. Obviously, manual application of the cement by brush or syringe in such cases is time-consuming and ineicient. Thus, it is a general object of the present invention to provide a novel applicator for applying liquid cement in a predetermined pattern on a plastic article.

One convenient method of applying liquid cement involves the use of a brous device, such as a wick, or the like, for absorbing a quantity of cement for subsequent direct transfer to an article to be cemented. The cementing uid of the exposed transfer edge eventually becomes contaminated with the substance to which the cement is applied which reduces the cementing quality of the cement, thus reducing the efficiency of transfer. It is a more specific obiect of the present invention, therefore, to provide a novel applicator for applying liquid cement which utilizes a fibrous tape Wick and which includes holding means which enables the wick being pulled up slightly and trimmed at will for providing a fresh applying edge.

It is another object of the present invention to provide a novel liquid cement applicator which incorporates a reservoir for containing a quantity of the cement.

It is another object of the invention to providea novel applicator for applying liquid cement in a predetermined pattern which utilizes a brous wick for withdrawing the cement from the reservoir and applying it to the part to be cemented.

It is another object of the invention to provide a novel applicator for applying liquid cement in a predetermined pattern which utilizes a single wick for applying cement in a plurality of spots.

The foregoing, along with additional objects and advantages, will be apparent from the following description taken in conjunction with the accompanying drawing, in which:

Figure l is a top plan View of an applicator conforming to the present invention;

Figure 2 is a vertical sectional View taken generally along the line 2-2 of Figure l and showing the applicator with a quantity of liquid cement therein;

Figure 3 is an enlarged Vertical section taken gen- VPatented hda1'.Y 18, 1958 ICE erally along the line 3-3 of Figure l and showing the` applicator with a quantity of liquid cement therein;

Figure 4 is an enlarged vertical sectional view taken generally along the line 4-4 of Figure 1;

Figure 5 is an enlarged vertical sectional view taken generally along the line 5 5 of Figure l;

Figure 6 is a side elevational View of a plastic cover for a calculator, the illustrated cover being typical of plastic parts to which liquid cement is to be applied in a predetermined pattern;

Figure 7 is a bottom plan view of the cover of Figure 6, showing liquid cement applied thereto; and

Figure 8 is an enlarged vertical sectional view taken generally along the line 8-8 of Figure 6 and showing liquid cement applied to the cover.

Referring to the drawing more particularly by means of reference characters, the numeral 10 designates generally an applicator constructed in accordance with the teachings of the present invention. The applicator 10 includes a shallow rectangular box 12, provided with a plate-like cover 14 which ts snugly within the box 12, as clearly illustrated in Figures 2 and 3. Both the box 12 and the cover 14 may be constructed of metal, or any other material which will not be dissolved or corroded by the liquid cement to be used therewith.

The illustrated applicator 10 is a production tool, and, hence, is adapted for use with a particular plastic article to which cement is to be applied. For illustrative purposes only, therefore, there is shown in Figures 6, 7 and 8 an article of plastic manufacture for which the illustrated applicator 10 is adapted to apply cement in a predetermined pattern. The plastic article, designated by the numeral 15, while generally plate-like in form, has four depending pintles 16 and four integral locating pins 18. It is desired that liquid cement be applied, not only to the free ends of each of the pintles 16 and pins 18, but also in the form of six side strips 20 and four end strips 22'. Returning now to the applicator 10, the cover plate 14 is, as best shown in Figure l, provided with a plurality of openings which correspond substantially in size, shape and relative location with the desired pattern of cement to be applied to the article 15. Thus, there are four holes 24 of a size and location for easy accommodation of the pintles 16; there are four holes 26 of a size and location for easy accommodation ofthe locating pins 18; and there are six slots 2S and four slots 3i) corresponding in size and location with the desired cement patches 20 and 22, respectively.

In addition to being provided with the above enumeratedopenings corresponding to the desired application of cement to the article 15, the cover plate 14 has mounted thereon a plurality of guide brackets or clips 32 shaped as clearly illustrated in Figures 3 and 4 and secured by means of rivets, welding, or the like, in the pattern best illustrated in Figure l. Thus disposed, the clips 32 serve as positioning guides for an article 15 emplaced as indicated by the broken outline of Figure l.

A table or platform 34, comprising a top panel 36 supported by end panels 38, is removably disposed within the box-like reservoir 12, as clearly illustrated in Figures 2 and 4. It will be noted that the table 34, while having substantially the same length as the reservoir 12, is sorncwhat narrower than the latter so as to leave ample room on each side for depending side portions 40 of a blanket Wick 42. This wick 42 extends over the top of the table 34 so as to be interposed between the cover 14 and the panel 36 of the table 34. Thus assembled, the cover 14, the wick 42, and the panel 36 of the table 34 are fastened together by means of countersunk screws 44 which pass through the cover 14 and wick 42 for threaded engagement with the panel 36.

As clearly illustrated in each of the Figures l through 5,v` .thwanaissf matabais pfoyidedrwifh, vertical.

holes which are in respective axial alignment with the holespreviously mentioned as being formed in the cover plata-14.1 It will be vparticularly noted, however, that.A

each ofi theV holes; in .the .'p'anel 36 is of substantially greater diameterithan thelsholefwith which it is aligned. Thus, a hole 46 .ofegrea't'endiameterfthanthe-holes 24 alignstwithY eachfofgtherlatter, and va hole 48 ofgreater diameter than thelholes` 26 .aligns Vwith Veach of Ythe latter. Despite thisgaligned arrangement of the holes 24, 26; 46,*v and 48, however, it willfbe observedpfrom Figures '2,3, and'5 that theVY blanket wick42'isnot perforated at these points, but extends solidly across these openings.

. VItfmaiy; be mentioned at this point that, in' addition to the holes iabovefmentionedjhe cover plate 14 is providedy with :a filler hole Slinralignment witha hole 52 formed in the panel 36, and .alsowith ahol-e 54'forrnedrin the blanket wick 42. A cork" 56 is provided -for closing this 'ller opening. Y

As best illustrated YVin-Figures 3 and'4,.th'e panel 36; inV addition tobeing providedwiththe'round openings abovementioned, is also provided :with slotted openings in alignment'with the slots 28 and 30 inthe cover plate i4. These openings', designated SSand 66, correspondingrespectively With the slots128and 30, are also' somewhat larger than their counterparts Vin the cover plate 14, so as: to provide'freeV traverse for lstrip'wicks 62 and `64 which'ex- Ytend upwardly throughrthe. appropriate slotswto project just above the uppergsurfaceof the cover plate 14, as ilof tl'ielcorkV 56.v The liquidcement in the reservoir 12v will, of course, saturatevthe lower ends of each of the strip wicks 62 and 64, and also thevdependingV portions 4010ith'e blanket wick 42. The'liquid cement will rise bycapillary action until the whole of these wicks are insaturated condition. VWith'the applicator 10 thus prepared, it is only necessaryV to'dispose'an article 15 -within the guideclips 32 and to press it downwardly toward the'coverplatej14'in order to apply cement in the desired pattern thereon. The depending pintles 16 and pins 18 engage the blanket wick 42 at the same time-the body portion of the article 15`engages thel projecting .portions of the strip wicks 62 and 64;A

Liquid cement may be applied by means ofthe applicator pin torone after anotherarticle 15, inasmuch asV the several wicks thereinv willserve to provide a continuous supply ofcement atthe points of application.

Preferably, the applicator-10 is frequently emptied and cleaned thoroughly, this being a simple operation due to;

the above-described construction which permitsthe Whole applicatorassembly to be liftedY right out of the reservoirllwitholltthe necessity of'disrnantling the, severaLparts,l v

The blanket wick is easily replaced when necessary, while the strip wicks 62 and 64 may be pulled up slightly and trimmed with shears, or the like, as often as necessary to keep the applying edges in good condition. l

Clearly, there has been described an applicator which fulfills the objects and advantages sought therefor.

The foregoing description andthe accompanying drawing have been given only by way of. illustration and'example. It is,k to be understood, therefore, that changes in the form of the elements, rearrangement of parts, and

the substitution of equivalent zelements, all of which will' be apparent to those skilled. in the art, are contemplated` as being within the scope of the present invention, which is limited only by the claims which follow.
